technical field

The invention relates to a remote decoupling device, in particular to a remote decoupling device for hoisting an underwater vehicle.

Background technique

Underwater vehicles have become a powerful tool for people to complete various underwater tasks. From pool commissioning, field testing to delivery to customers, the release system of underwater vehicles accompanies almost the entire life cycle of underwater vehicles. At present, the common release and recovery methods of underwater vehicles include cranes, A-frames, slideways, central wells, and diving platforms. Among them, the cranes are widely used in the form of single-arm cranes and door cranes, whether they are port test bases or sea test mother ships, due to their simplicity and versatility; A-frames, central wells and submersible platforms are mainly equipped on on the test mother ship; the slipway system is a release and recovery system designed for a single underwater vehicle. In addition to the release and recovery system of the slideway and the diving platform, the release process of other systems is actually "hanging", that is, the process of unhooking is involved. In the past, the method of manual unhooking was commonly used. Manual unhooking not only It is laborious and time-consuming. In addition, the biggest problem with manual decoupling is that the personal safety of operators cannot be guaranteed, especially in harsh sea conditions. This has given birth to the application of decoupling devices in underwater vehicle release systems. Scientific research units in the field of underwater vehicles have designed different decoupling devices according to the characteristics of their respective underwater vehicles.

Returning to the sleeve leads to failure of decoupling. The present invention uses a cubic shell to envelop the suspension ring of the underwater vehicle, which can prevent the main body of the suspension ring from tilting too much before decoupling, and ensure that the load-bearing rod can bounce back into the guide sleeve smoothly.
